A cyclin called cyclin E forms a complex with a cyclin-dependent kinase called Cdk 2. This complex is important for the progress

ion of the cell from G1 into the S phase of the cell cycle. Which of the following statements is most likely to be correct? A. The amount of Cdk 2 is greatest during G1. B. The amount of unbound cyclin E is lowest as the cell enters S. C. The activity of the cyclin E/Cdk 2 complex is highest during G2. D. The amount of unbound cyclin E is greatest during the S phase. E. The amount of Cdk 2 is greater during G1 compared to the S phase.

Answer:

B. The amount of unbound cyclin E is lowest as the cell enters S.

Explanation:

The reproduction of the cell is a cycle that it regulates by itself, depending the  demand of a certain cell.

In the case of the mitosis, in Each change from G1 to S to G2 to M is regulated by some proteins like the cyclin.

In the case of the cdK2 is ncessary to pass the control point to pass from the stage G1 to the stage S.

Another characteristic of the cyclins, is that these proteins are synthetized and degraded constantly during the hole process.

Hope this is a useful info
